MCKey

The MCKey function handles keyboard events for a movie controller. You can call this function only if you have enabled keystroke processing in the controller. By default, keystroke processing is turned off when you create a movie controller. You can enable and disable keystroke processing using the mcActionSetKeysEnabled action with the MCDoAction function (described on page 2-46).

DESCRIPTION
